WTF is this engine?

I am so confused. This engine looks just like a D17, but it's apparently a D15B? WTF is this? Is it just a D17A with a different name or something? Maybe it was mislabeled?

Is something wrong?

Honda made more than 3 different engines.
Honda makes more engines than any other company in the world

I did Google it. I was only finding D15B engines like this. When they are called the same thing but are clearly different, how do I know which one they are talking about?

=============================================

D15B with 3-Stage VTEC

This section does not cite any sources. Please help improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed. (July 2013) (Learn how and when to remove this template message)

3-Stage VTEC is a version that employs three different cam profiles to control intake valve timing and lift. Due to this version of VTEC being designed around a SOHC valve head, space was limited; so VTEC can modify only the opening and closing of the intake valves. The low-end fuel economy improvements of VTEC-E and the performance of conventional VTEC are combined in this application. From idle to 2500-3000 RPM, depending on load conditions, one intake valve fully opens while the other opens just slightly, enough to prevent pooling of fuel behind the valve, also called 12-valve mode. This 12 Valve mode results in swirl of the intake charge which increases combustion efficiency, resulting in improved low end torque and better fuel economy. At 3000-5400 RPM, depending on load, one of the VTEC solenoids engages, which causes the second valve to lock onto the first valve's camshaft lobe. Also called 16-valve mode, this method resembles a normal engine operating mode and improves the mid-range power curve. At 5500-7000 RPM, the second VTEC solenoid engages (both solenoids now engaged) so that both intake valves are using a middle, third camshaft lobe. The third lobe is tuned for high-performance and provides peak power at the top end of the RPM range.

I don't know which engine that is. I looked up pictures of both, but neither one look like the engine in question.

Re: WTF is this engine?

Could be a random engine pic. Looks like an old Accord engine? Could be anyf'nthing.

If you cannot read the engine code stamped on the block, you can only guess.

I can read the code. It's a D15B that looks exactly like a D17A. Maybe it was mislabeled?

Re: WTF is this engine?

Oh, I was looking at the one with the black valve cover.


D15x looks like your D17x because it's of the same engine family and probably even similar years, just smaller displacement version that was used in other world markets. That engine was never used in the USA.

I see. That makes sense. Thanks. Any idea where I could find specs for it?

A Japanese car? Some other country?


You would really need to get the actual code stamped on that particular block, so we all might get to find out what it is.
All you have is a blurry ebay picture and a seller writing up whatever he wants you to read.



FWIW it doesn't really even have to be for a car at all. Could be an industrial engine for all we know.
